Experimental results for the burning characteristics of fiber-supported, n-decane droplets burning in air under a slow forced convective flow in the form of single, isolated droplets, and interacting, two-droplet, linear arrays are presented in this study. The experiments were carried out in a microgravity environment onboard the Space Shuttle Columbia during the MSL-1 mission to eliminate the influences of buoyancy. The droplet sizes in these experiments varied from 2 to 5 mm in diameter and the imposed forced convective velocities ranged from 0 to 25 cm/s. Small ceramic beads anchored the droplets during the forced convective experiments. The results show that the interactive effects between the droplets reduce the burning rates for both the upstream and downstream droplets in a linear array. In particular, the burning rates for the downstream droplet could be reduced by as much as 30percent compared to a single droplet burning under similar conditions.
